Detailed Description

Open Inventor engine to write scene representation to file.

Suppress warning suppressions in Visual C++ and include all non ML includes here Open Inventor engine to write scene representation to file

The STL file format was implemented by Stephan Zidowitz. The Inventor formats use the Open Inventor SoWriteSction to write the scene. The VRML formats are only supported when compiled with TGS Open Inventor
